I've shared quite a few things that are off-the-wall. One that got a lot of attention was this CO who mentioned that two sisters became lesbians because they decided to watch Mexican novelas together.
Also, I remember an elder who visited to give a talk, who mentioned that a brother was preaching in a dangerous area, and somebody shot him, but angels protected him and the bullet bounced from his head.
Then there was what I consider one of the worse narcissistic personality disorder I've ever met in person. This elder said that he is Jehovah during a talk.
This other elder trained himself to eat leaves because he was convinced that leaves were the only thing left during the great tribulation (He had 13 children; to me that's the real origin of the idea of eating leaves).
Another elder loved to tell a rather diverse wealth of stories involving demons attacking JWs for being loyal. One that I remember (I was 7, and it was so inappropriate for me to be exposed to that kind of information at that age). was about a loyal JW woman who was always being attacked by demons because her husband wasn't and he was attracting them. He said that one night the demons were rubbing and licking her breasts, and touching her lady parts.
